I'd report him. That could be YOU he's talking about next time.

I was sitting in a doctor's waiting room a few years back, and his receptionist/secretary was on the phone. I heard her say, "Hello, is this "Jane Smith"? This is Dr. C's office, and he wants you to discontinue the (med) and up the dosage of the (med)..." and so on.

Well, I KNEW "Jane Smith", and I was horrified. It could have been me! I told the doctor, but I still was uncomfortable there and switched to another practice.
